T aZZ whom it may concern:

Be it known that I, TALBOT O. DEXTER, a

'citizen of the United States, residing at Pearl River; in the county ofRockland and State of New York, haveinvented certain new and usefulImprovements in Folding-Machines, of

' which the following is a specification.

four completely-cut signatures are delivered at once.

zoaing means.

In the operation of the preferred construc- The sheet then passes arounda cutting-cylinder and isdivided longitudinally into four strips orsheet-sections, which are arrested 'by suitable gages in-position to beacted upon by four independent sheetdeflecting drop-roller mechanisms,which successively deflect the said strips or sheet-sections to anassembling-conveyer, which carries the strips or sheet-sections to thefolding-gage -and assembles them. Each strip or sheetthe folding-gage,an immediately after this section is individuall registered as itreaches registration the folding mechanism folds the assemblage ofsheets longitudinally and passes the same to the final-cutting devices,which sever the folded assemblage of strips or sheetsections into fourout signatures of sixteen pages each. The signatures are delivered tothe ordinary packing-boxesin the manner now commonly used.

Inorder that my invention may be fully understood, I will firstdescribe-the-same with reference to the accompanying drawings andafterward point out the novelty more par-.

1 1 ticularlyin the anneXedclaims.

In said drawings, Figure 1 is a general plan view of my improvedfolding-machine, some of the parts (which are well known in foldingmachinery) being omitted for the sake of clearn'ess.

Fig. 8 is a detail sectional view taken on the line a a of-Fig. 7looking fromright to left. Fig. 9 is a diagrammatic view illustratingthe relation and operation of the sheet-deflecting drop-rollermechanisms and the'assembling and final-fold mechanisms.

' My improved folding mechanism may be built upupon any suitableframework, such as shown in the accompan ing drawings, which consists,essentially, of t es'ide frames 1 and 2,

the front and back frames 3 and 4, and the auxiliary bracket-frames 5and 6, projecting from side frame 2 and supporting the folding andassembling mechanisms and packingboxes. These frame-pieces are allrigidly secured together and'properly braced by tie- -bolts andauXiliaryframe-bars to constitute afirm structure.

1O is the main power-shaft of the machine, suitably journaled inside-frames l and2 and provided with any. suitable means, (not shown,)such as fast and loose pulley mechanism,-for driving it. All of theoperative parts ofthe machine are driven fromthe power shaft 10 throughthe mechanism which will hereinafter be described.

"The sheets to be cut and folded into completely-cut signatures are fedsuccessively by hand or by automatic feeding-machinery from thefeed-table 15 (shown in Fig. 2) to the usual feeding-in drop-rollermechanism, consisting of the lower constantly-rotating feed-roller 16and the upper drop-roller 17 'The lower roller. 16 is journaled at itsopposite ends in the forwardly-projecting bracket extensions upon thefeed-roller 35 ust prior to the opershaft also carries a gear-wheel 27,by which- Y journaled in the brackets 32,

1 and 2 of the side frames 1 and 2, the journal-shaft of the rollerprojectingbeyond the bracket extension 1 to support a gear-wheel 18,which is keyed to it. The drop-rollers 17 are mounted upon a shaft 19,journaled in the forwardly-projecting rock-arms 20, keyed to arock-shaft 21. This rock-shaft 21 is journaled in the brackets 1 and 2and carries at one end a rock-arm 22, connected with a pitman 23, whichis actuated by a cam! 24,. mounted upon a short shaft 25, which isjour-' naled in the side frame 1 at 26. The short the cam 24 isconstantly rotated through gearing hereinafter referred to.

' A series of tapes 30 pass around the roller 16 and around the smallertape-roller 31, adjustably mounted upon the side frames 1 and 2, asshown in Figs. 1 and 2.

33 represents a series of sheet-supportin slats leading from the tapes30 to a secon drop-roller mechanism consisting of the lower feed-rollers35, journaled in the side frames 1 and 2, and the upper drop-rollers 36,mounted upon the shaft 37, 'ournaled in the rock-arms 38,. secured torock-shaft 39, which is journaled in the side frames of the machine at39. The under roller 35 of this second droproller mechanism has securedto its shaft a gear 40, by which it is constantly rotated throughgearing hereinafter explained. The rock-shaft 39 of the drop-roller haskeyed to its projecting endat the left a rock-arm 41, carrying anantifriction-roller 42, which runs in peripheral contact with a cam 43,keyed to a short shaft 44, journaled in the side frame 2. This shortshaft 44 also carries a large gear 45, meshing with a smaller gear 46,keyed .to the projecting end of shaft 47 of the circumferentially-gmovedcutter-roll 60, hereinafter referred to. A secondcam 48 is also mountedupon the short shaft 44 for controlling the drop-gages 49, which areadjustably mounted upon a rock-shaft 50, journaled in the side frames ofthe machine and carrying at one end a rock-arm 51, having anantifriction-roller 52, which runs in peripheral contact with the saidcam 48. The dropgages 49 arrest the sheet with its leading edge ation ofthe drop-roller mechanism 35 36 to straighten the sheet and give timefor the side registry of the sheet by any suitable side-registrymechanism, such as indicated at 55. This side-registering mechanlsm maybe of any suitable construction; but I prefer to employ the mechanismcovered by Patent No. 759,972, granted to me May 17, 1904.

Parallel with and adjacent to the lower feed-roller 35 is mounted alarge circumferentially-grooved cutter-cylinder60, whose shaft 1 47,above referred to, is j ournaled in the side frames 1 and 2 of themachine.

61 is a cutter-shaft extending parallel with lar cutters 62, each one ofwhich is adapted to project into and operates in one of the rooves ofcutter-cylinder 60, the sheets bemg cut into strips as they pass betweenthe cylinder 60 and circular cutters 62. The cylinder 60 iscircumferentially grooved at intervals throughout its length, so thatthe circular cutters 62 can be adjusted upon their shaft to cooperatewith any of the grooves, so as to cut the sheet into strips of anydesired width.

65 and 66 are tape-rollers j ournaled in the side frames of the machineabove and in the rear of the cylinder 60.

67 represents a second series of conveyertapes which pass over thetape-rollers 66 and 65 and half around the cutter-cylinder 60 uponopposite sides of the cutters 62, said tapes 67 also passing around atape-roller 68, journaled in the forward end of the machine beneathfeed-roller 16, and then around the tightening-rollers 69 andidler-rollers 69 back to the first-mentioned tape-roller 66. Theseconveyer-tapes 67 constitute a second conveyer for passing the sheetsthrough the cutting mechanism just described and returning them in aplane beneath and parallel with the first conveyer-tapes 30 intoposition for the operation of the sheet-deflectin droproller mechanisms,which will now be described.

Beneath the plane of the conveyer-tapes 67, adjacent to and parallelwith the front and rear frames of the machine, I provide the track-bars70, which extend transversely of the machine. Track-bars 70 are groovedlongitudinally to receive the sliding bl0cks'71, in which are journaledthe under feed-rollers 72. The feed-rollers 72 extend longitudinally ofthe machine between the track bars 7 O and constitute, with the blocks71, adjustable carriages, each pair of blocks 71 being also connected bya small rotary shaft 73, on the opposite ends of which are mountedpinions 74, which mesh with short rack-bars 75, secured to the frontfaces of the track-bars 70. One end of each shaft 73 is squared, asshown in Fig. 6, to receive a wrench or key by which the shafts can berotated to shift the carriages in either direction upon the track-bars.Each block 71 has a downwardly-projecting flange 71*, to which issecured an angle-plate 71 which engages the under edge of the track-barfor confining the block upon the bar.

The blocks 71 at the forward end of the machine have upwardly-projectingbrackets 80, in whichare journaled the forward ends of rock-shafts 81,carrying rock-arms'82, on which are journaled drop-rollers 83. The rearends of the rock-shafts 81 are journaled in blocks 84, all but one ofwhich are adjustably mounted upon the frame-bar 85, said bar 85 beingslotted longitudinally to receive ribs or flanges 84 which project fromthe rear sides of the blocks 84. The bar 85 extends parallel to the reartrack-bar 70 and is spaced therefrom to support the rock-shafts 81horizontal and allow free passage of the sheet-section fromcutter-cylinder 60 on tapes 67.

The second carriage from the left-hand side of the machine, as shown inFigs. 1, 7, and 9, is preferably stationary, and the other carriages areadjustable transversely of the machine with relation to the stationarycarriage. At the front of the machine the supports for the drop rollerrock-shafts are directly connected with the sliding blocks 71 of thecarriages, since there is no necessity for separatin these parts inviewof the fact that the l eading ends of the strips or sheetsections arearrested by the gages. mounted upon said forward ends of the carriages.The rear ends of the carriages, however, are differently constructed, soas to separate the supports for the drop-roller rock-shafts and thesupports for the under feed-rollers to allow the strips orsheet-sections to pass freely between the lower feed-rollers and-thedroprollers, as just referred to. It is on this account that the rearends of the drop-roller rock-shafts are mounted in blocks which aresupported upon the rail 85. At thesame I tune it is necessary tosimultaneously adjust corresponding under feed-roller.

each set of drop-rollers with its under feedroller, and to properlyeffect this adjustment bothends of each drop-roller rock-shaft must moveexactly in unison with both ends of the To accomplish this, I haveadopted the arrangement shown in Figs. 7 and 8, in which thesupporting-block 84 of each drop-roller shaft is connected with thecarriage of its under feedroller by means of an angular rod or yoke 90,

90, or 90*, each of which is extended to one side beyond the path of thestrips or sheetsections, so as not to interfere with their free passagethrough the machine. With this arrangement it will be observed that anydroproller mechanism can be accurately adjusted At the forward end ofeach carriage is an adjustable gage 95, which is supported upon thecarriage-bracket 80 by means of adjustingscrews 96, held in the desiredadjusted position by thumb-nuts 97.

Each under feed-roller 72 has keyed to its projecting shaft or journal abevel-gear 100,

which is in constant mesh with a similar gear 101, splined to a shaft102, extended transversely of the machine. A forked arm 71 extends fromblock 71 and engages groove 101* of gear 101 to cause the gear. 101 tomove upon its shaft when the drop-roller carriage is adjusted. The shaft102 has keyed to its outer end at the right of the machine a gear-wheel103, through which it is driven by mechanism hereinafter described; Theshaft of each under feed-roller 72 is also provided with a pinion 105,meshing with a larger gear 106, keyed to a short shaft 107, journaled inthe bracket 80 of the carriage. This shaft with a rock-arm 112, carryingan antifrictionroller 113, which runs in peripheral contact with the cam111. By this means the droprollers are operated. representssheet-defleeting fingers, also mounted upon the rockshaft 81 adjacentthe drop-rollers 83.

116 represents inclined guide-fingers secured to a crossbar 117 1n thesame vertlcal planes as the deflecting-fingers 115, their pur.

pose being. to guide the sheet-sections down to the plane of the thirdset of conveyertapes, which will now be explained.

120 is a tape-roller journaled in the front and rear frames 3 and 4 ofthe machine and extending longitudinally of the machine ad.- jacent toits right-hand side.

121 represents the belt-tighteners, and 122 represents idler-pulleys. Atthe left-hand side of the machine are arranged the knurled roller 123and large tape-roller 124 and the idler-roller 125, all of which extendlongitudinally of the machine.

126 represents the third set of conveyertapes extended around therollers 120 121 122 123 124 125. These tapes 126 constitute the finalasse1nblingconveyer upon which the strips or sheet-sections are deposited successively by the sheet-deflecting droproller mechanism abovedescribed.

130 and 131 are tape-rollers.

132 represents guide-tapes which pass around rollers 130 and 131 andknurled roller 123 for confining the sheet-sections in the proper pathin engagement with tapes 126, so as to assist the knurled roller indepressing the rear edgeof each sheet-section to insure the overlappingof the successive sheet-sections in assembling them one upon another.

135 is a plate or support upon which the sheets are assembled inreadiness for the final registry and folding operations.

136 is the folding end gage.

137 and 138 are belt-pulleys, and 139 represents tapes passing. aroundthe pulleys 130, 131, 137, and 138 and knurled roller 123 to properlyconfine the sheet-sections upon the folding table or support, so as toprevent the said sheet-sections from curling up or rebounding as theyare fed into place.

140 is the folding side gage.

141 is a rotating final side registry provided with four rubber-tippedregistering fingers to successively engage the four sheetsections uponthe folding-table. This final registry device is operated throughsuitable gearing, with an auxiliary shaft 142 geared with the maincam-shaft 143 of the machine, as shown in Fig. 3.

The table or support 135 is provided with the usual longitudinal slot(not shown) to receive the folding-knife 151, which is mounted upon therock-arms 152, projecting from the rock-shaft 153. This rock-shaft 153is operated by cam 154 through the medium of a rock-arm 155 and link156. The knife 151 strikes the assemblage of sheet-sections through thetable-slot into'the bight of the folding-rollers 160, which arejournaled beneath the table 135. The folded assemblage of sheet-sectionsthen passes through the compression-rollers 161 and cutting-rollers 162,by which it is cut into four completelycut signatures, which aredroppedinto the four parallel packing-boxes 165, extending horizontallyat right angles to the machine at the left.

The packing-boxes 165 are supported upon an auxiliary frame bolted tothe main frame of the machine, and each packing-box is provided with theusual yielding abutment, (not shown,) against which the signatures arepacked by the horizontally-reciprocating packingfingers 167 andcooperating vertically-reciprocating retainingfingers 168.

Retaining-fingers 168 are mounted upon the vertical slide 170, suitablymounted in the frame, which slide is actuated by rockarm171, projectingfrom a rock-shaft. 172, journaled in the machine-frame at 173 andconnected, through the rock-arm 174, with a link 175, which is moved inone direction by a spring (not shown) and in the other direction by cam177, keyed to the cam-shaft 143 of the machine. The horizontally-reciprocating packer-fingers 167 are mounted upon horizontal slidesconnected, through links 176 and rock-arms 176, with the rock-shaft 178, journaled in the bracket 178. This rock-shaft 178 is connected,through rockarm 179, with link 180, which is moved in one direction by aspring (not shown) and in the opposite direction by the cam 182, keyedto the cam-shaft 143 of the machine.

The mechanism for driving the several operative parts of my improvedmachine will now be pointed out,

Keyed to the main power-shaft 10, adjacent its right-hand end, is abevel-gear 200, which meshes with a similar gear 201, keyed to acounter-shaft 202, which extends longitudinally of the machine along therighthand side and is journaled in the bracketbearings 203. Thiscounter-shaft 202 has on its forward end a bevel-gear 204, which mesheswith asimilar bevel-gear 205, which is secured to a gear-wheel 206, (seeFig. 3,) the bevel-gear 205 and gear-wheel 206 being suitably journaledupon a stud or bearing projecting from the side frame 1 of the machine.The gear 206 meshes with and drives the gear 103 upon shaft 102, fromwhich the sheet-deflecting drop-roller mechanisms are operated. The gear103 also meshes with the intermediate gear 207, which in turn mesheswith the gear 18 on the shaft of feedroller 16, above referred to. Keyedto the shaft 102 outside of gear 103 is a similar gear 210, which drivesthe gear 27 through intermediate gears 211 and 212 for operating thefirst drop-roller 17.

Returning to the power-shaft 10 ,it will be observed thatv adjacent toits left-hand end in the interior of the machine it is'provided with abevel-gear 215, which niesheswitha similar bevel-gear 216, keyed to therear end of counter-shaft 217, extending longitudinally of the machineand provided at its forward end with a gear-Wheel 218, meshing withintermediate gear 219, from which the largefeed-roller 124,folding-rollers 160, compression-rollers161, and cutting-rollers 162 areall driven, the arrangement of the gears being shown clearly in Fig. 3.Power-shaft 10 also carries adjacent to its right-hand end a smallgear-wheel 220, which meshes with and. drives the large gear-wheel 221upon the right-hand end of cam-shaft 143, above referred to. This gear221 meshes with and drives the gear 222, keyed to the shaft 47 of thecutter-cylinder 60, above referred to. The gear 222 also drivesthecutter-shaft 61 through a gear which is not shown. A smaller gear 223 isalso keyed to the shaft 47 of the cutter-cylinder and meshes with thegear 40 upon the lower feed-roller 35. The tape-roller 66 has keyed toits outer end a gear (not shown) which is driven by an inter- Y mediategear (not shown) meshing with the large gear 221 just referred to.

The operation of my improved machine may be briefly described asfollows: The printed sheets which are tobe cut and folded intocompletely-cut signatures for a book, pamphlet, or magazine are fedsuccessively by hand. or by automatic machinery from the feed-table 15through the drop-roller mechanism 16 17, which feeds the sheets tothefirst conveyer-tapes 30. The sheets are arrested. by the front gages 49,and the side-registry mechanism 55 positions them in the usual manner.Immediately after the registry of the sheet the second drop-rollermechanism 35 36 comes into play to pass the sheet to the cutter-cylinder60 and the second conveyer-tapes 67, with the result that the sheet iscarried half-way around the cylinder 60 and cut into four strips orsheet-sections, which are carried against the gages 95 of thesheet-deflecting drop-roller mechanisms '72 83 115. Immediately afterthe arrest of the sheets by the gages 95 the drop-roller mechanisms justreferred to come into play to feed off the strips or-sheet-sectionsSlaterally, the said mechanisms operating successively to deflect thesheet-sections onto'thethird or final conveyer-tapes 126, which carrythem to the final assembling, folding, and delivery mechanisms. In Fig.9 the successive action of the sheet-deflecting drop-roller mechanismsis illustrated, the controlling-cams of the several sets of drop-rollersbeing shown in progressive relative positions. The sheet-- sections Spass separately over the knurled roller 123, which quickly depresses therear edge of each sheet-section, so as to insure the leading edge of thesucceeding section overlapping the preceding section. The foursheet-sections are arrested by the final-fold gage 136 and successivelyregistered by the rotating side register 141. Immediately following thisaction the folding-knife 151 operates to strike the assemblage ofsheet-sections into the bight of the folding-rollers 160, the fold beingmade longitudinally of the length of the sections. The sections are inthis way folded one within another and are passed through compressionand cutting rollers, by the action of the latter of which the foldedsections are separated into four completely-cut signatures, which aredelivered in the packing-boxes by the mechanism described.

Completely-cut signatures with any numleer of pages Within reason may beproduced with my improved folding-machinc by simply increasing ordecreasing the number of cutters and deflecting drop-roller mechanismsand relatively adjusting these parts to operate upon the sheet-sectionsof the desired size.
